Shinjaku 眞寂 / 真寂 (Heian or Kamakura period; lifedates uncertain) — Japanese Esoteric scholar, author of the Yújí zǒng-xíng sī-jì 瑜祇總行私記 (KR6j0033, T61n2229) — private notes on the general practice of the Yújí jīng 瑜祇經 (Vajraśekhara-yoga-sūtra, KR6j0031, T18n0867). The text is a substantial commentary on the Vajradhātu-yoga ritual tradition.
He should not be confused with Shinjaku Shinnō 真寂親王 (a Heian princely Esoteric scholar; DILA A000951, author of T2469 Bùguànlíngděng jì) who shares the same name but is identified separately in the DILA authority.
The Yújí zǒngxíng sījì is his only attested work in the Taishō / canonical corpus. No other biographical data are preserved.
